Title: Thermoreacting device
Inventor: MIYAZAKI OSAMU
IPC: H01H37/58
Filed: 1992-07-01
Abstract: PURPOSE:To prevent malfunctioning of a thermoreacting device that could be caused by the body fluid of cockroaches, etc., entering the device from the outside by applying a material with high non-stickiness such as fluororesin to the respective attracting faces of a temperature element and a magnet. CONSTITUTION:A material with high non-stickiness such as fluororesin is applied to the attracting surface of at least either one of a temperature element 1 made of a ferromagnetic substance having Curie temperature and a magnet 2 attracted to the temperature element 1, so as to prevent the temperature element 1 and the magnet 2 from being stuck to each other by the body fluid of cockroaches, etc. A spring 5 for providing resiliency is mounted between the temperature element 1 and the magnet 2. As the ambient temperature rises, the temperature of the temperature element 1 also rises and the temperature element 1 abruptly looses its magnetism at the Curie temperature, so the magnet 2 is pushed downward by the spring 5 and power supply is cut off by control of a switch connected to a rod 7.

Abstract: PURPOSE:To obtain the titled device having a lifetime of the same as convention or more even in power-up by a method wherein, using Sn-Sb solder as the mounting material connecting a power chip within a copper chip, the copper chip to an in insulation substrate and the insulation substrate to a heat sink are connected with eutectic solders. CONSTITUTION:The power chip 21 is connected to the copper chip 22 with an Sn-Sb solder (Sb=8.5%) 31, and the copper chip is connected to the insulation substrate 23 with an eutectic solder 32; further; the insulation substrate is connected to the heat sink 24 with an eutectic solder 33. This manner allows the strain caused by the difference in coefficient of thermal expansion between the power chip and the copper chip generating by heat cycles evolving in the power chip to be aoplied to the solder part therebetween. However, in the case of Sn- Sb solder, elongation is larger then the case of using the conventional Sn-Sb solder; therefore, the degree of fatigue caused by the repeated strains of the solder part becomes relived, and the lifetime of the power chip caused by thermal fatigue becomes prolonged.

Filed: 1991-06-20
Abstract: PURPOSE:To extend a viscosity range of ink in use and improve a productivity of liquid crystal elements in the production of liquid crystal elements using a transfer printer by removing excess ink from a color ink spreading member and an object member. CONSTITUTION:In a transfer printer for spreading color ink to an object member by a blade-form color ink spreading member, excessive residual ink 3a spread onto a spreading roller 2 is scraped into a groove part 2a by a doctor blade 1. Furthermore, the ink is scraped by the edge of the groove part 2a. The groove part 2a of the spreading roller 2 may be formed in parallel to a rotating shaft of the roller 2, but it is preferable that the groove part 2a is formed obliquely to the rotating shaft of the roller 2 for an ink scraping effect and the protection of the doctor blade 1. In this manner, a viscosity range of ink is extended so that the ink can be printed uniformly without spread irregularities, and a change in film thickness at the time of continuous printing caused by an ink viscosity increase is prevented and, thus, a continuous operating time is improved to a great extent.
